All you need is:
2 lego platforms
cord from an old table lamp
hot glue gun
fabric (optional) - scissors - straight pins
Next you can make a design if you would like. I chose to do a checker design.
Start building the middle section up.
Now , using the lamp cord, feed it through the middle. So you get a rough estimate to how tall you want your lamp to be.
I kept at this until it was about 16 sections.
(That way the cord can be hidden and it will keep it from being on a slant.
Also as you can see I also brought the sides in a bit for a better fit.
So basically inverse the colors each time.
So continue doing this until you reach about 11 layers.
